Senior Full-Stack Developer — Custom Advisor Dashboard and CRM Platform (Next.js, MongoDB, Airtable)

We are building a custom internal platform for our travel advisor network. This is not a website or a Webflow project. This is a production-grade full-stack application built in Next.js and TypeScript with MongoDB Atlas as the primary database and Airtable as the CRM and operations layer. The platform includes a role-based advisor dashboard, a super admin dashboard, a custom booking submission form, commission tracking and tier logic, five admin report types with CSV exports, secure invoice file storage, transactional email workflows, and integrations with Airtable, Webflow CMS, Mailgun, Cloudinary, and a private object storage service such as AWS S3 or Cloudflare R2. We have a detailed internal technical proposal covering architecture, phased delivery plan, data models, role and permission structure, milestone definitions, and cost modeling. You will receive the full document before any engagement begins. This is a fixed price milestone based engagement across five phases over approximately eight weeks. All source code, accounts, and assets are owned by Xullu throughout the project. Do not apply with a generic proposal. Your application must include a live production Next.js application you have built, your approach to Airtable API caching for high volume reporting, your approach to secure financial document storage with server side access control, and your fixed price broken down by milestone. Budget range is $10,000 to $14,000. We are not looking for the lowest rate. We are looking for the most qualified.
